Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of concrete production, in particular to a sand and gravel feeding bin for concrete production. Background Art
[0002] Concrete, abbreviated as concrete, is a general term for engineering composite materials that are cemented into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering.
[0003] In the process of concrete production, sand and gravel aggregates need to be discharged through the discharge hopper to the surface of the conveyor belt, and then transported to the mixing tank for concrete preparation. Since there are more materials stored in the discharge hopper and the pressure generated on the top is relatively large, it is easy to cause compaction at the bottom outlet, causing blockage of sand and gravel aggregates, which in turn leads to a slower sand and gravel discharge speed, affecting the efficiency of concrete preparation.
[0004] Therefore, it is necessary to invent a sand and gravel lower silo for concrete production to solve the above problems. Utility Model Content
[0005] The utility model aims to provide a sand and gravel feeding bin for concrete production, so as to solve the problem that the bottom outlet is easily compacted, resulting in blockage of sand and gravel aggregates, which in turn leads to a slow sand and gravel feeding speed and affects the concrete preparation efficiency.
[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sand and gravel feeding silo for concrete production, comprising a feeding silo bucket, a nylon plate is fixedly connected to the interior of the feeding silo bucket, a first feeding pipe is fixedly connected to the lower end of the feeding silo bucket, a first vibration motor is fixedly installed on the side wall of the feeding silo bucket, an aggregate scale is arranged on the lower side of the feeding silo bucket, a second feeding pipe is fixedly connected to the lower end of the aggregate scale, a third feeding pipe is connected to the lower side of the second feeding pipe, a second vibration motor is fixedly installed on the side of the aggregate scale bucket wall, and a conveyor belt is arranged on the lower side of the third feeding pipe.
[0007] By adopting the above technical scheme, the nylon plate is closely attached to the inner wall of the discharge hopper, thereby improving the smoothness and wear resistance of the inner wall of the discharge hopper. At the same time, the first vibration motor vibrates the discharge hopper and the nylon plate, so as to shake out the internal materials and discharge them downward quickly. The aggregate scale is used to weigh the discharged materials, and then the materials are discharged to the surface of the conveyor belt through the second discharge pipe and the third discharge pipe. At the same time, the second vibration motor shakes out the materials inside the aggregate scale, so as to discharge the materials quickly. The third discharge pipe accurately guides the materials to the surface of the conveyor belt to avoid the dispersion of the materials, and the conveyor belt transports the materials.
[0008] Optionally, a plurality of threaded holes are provided at the upper end of the discharge hopper, and a plurality of connection holes are provided at the upper end of the nylon plate.
[0009] Optionally, a fixing screw is inserted into the interior of the connecting hole.
[0010] Optionally, the fixing screw passes through the connecting hole and is threadedly connected to the threaded hole.
[0011] By adopting the above technical solution, the nylon plate is pressed tightly against the inner wall of the lower hopper, and then the fixing screws are inserted into the connecting hole and the threaded hole in turn, and the fixing screws are turned to thread the lower end of the fixing screws with the threaded hole, thereby fixing the nylon plate inside the lower hopper.
[0012] Optionally, a plurality of groups of connecting rods are fixedly connected to the side walls of the lower hopper, and a first connecting block is fixedly connected to the lower ends of the connecting rods.
[0013] Optionally, a buffer spring is fixedly connected to the lower end of each of the first connecting blocks.
[0014] Optionally, a plurality of groups of second connection blocks are fixedly connected to the upper end of the aggregate scale, and the lower end of the buffer spring is fixedly connected to the second connection block.
[0015] By adopting the above technical solution, the connecting rod and the buffer spring cooperate to suspend the aggregate scale on the lower side of the lower hopper. The lower hopper stores the materials, the aggregate scale weighs the materials, and the buffer spring prevents the first vibration motor and the second vibration motor from affecting each other.
[0016] Optionally, pneumatic gate valves are provided inside the first material discharge pipe and the second material discharge pipe.
[0017] By adopting the above technical solution, the pneumatic gate valve is used to control material discharge.
[0018] In the above technical solution, the technical effects and advantages provided by the utility model are:
[0019] 1. The utility model improves the smoothness and wear resistance of the inner wall of the lower material hopper by clinging the nylon plate to the lower material hopper. At the same time, the first vibration motor vibrates the lower material hopper and the nylon plate to facilitate the rapid discharge of the internal materials downward. At the same time, the second vibration motor vibrates the bucket wall of the aggregate scale to further increase the material discharge speed, so that the materials are quickly transmitted to the surface of the conveyor belt, thereby improving the concrete preparation efficiency. It solves the problem that due to the large amount of materials stored in the lower material hopper, the pressure generated above is large, which easily leads to compaction at the bottom outlet, causing blockage of sand and gravel aggregates, and then slowing down the sand and gravel discharge speed, affecting the concrete preparation efficiency.
[0020] 2. The utility model arranges an aggregate scale at the lower side of the feeding hopper. The material discharged from the feeding hopper first slides into the inside of the aggregate scale. When the material inside the aggregate scale reaches a specified weight, the feeding hopper stops discharging the material. At this time, the aggregate scale discharges the material inside it downward, thereby improving the accuracy of the feeding hopper discharging the material. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Among them, during use, the pneumatic gate valve inside the first discharge pipe 13 is opened, and the pneumatic gate valve inside the second discharge pipe 22 is closed. At this time, the material inside the discharge bin 1 slides downward, and the material inside the discharge bin 1 is vibrated by the first vibration motor 15, and at the same time cooperates with the nylon plate 11 to increase the discharge speed of the material inside the discharge bin 1.
[0031] At the same time, the material discharged from the discharge hopper 1 accumulates inside the aggregate scale 2, and the aggregate scale 2 weighs the weight of the discharged material and transmits the weighing information to the inside of the controller. When the weight reaches the specified threshold, the controller closes the pneumatic gate valve inside the first discharge pipe 13 and opens the pneumatic gate valve inside the second discharge pipe 22. At this time, the weighed material is discharged downward. During the discharge process of the aggregate scale 2, the second vibration motor 23 vibrates the bucket wall of the aggregate scale 2 to increase the discharge speed.

The screw connection facilitates the replacement of the nylon plate 11, and the nylon plate 11 is pressed against the inner wall of the lower material hopper 1 to improve the smoothness and wear resistance of the inner wall of the lower material hopper 1.

During the discharge process, the second vibration motor 23 vibrates the hopper wall of the aggregate scale 2 to facilitate the rapid discharge of the weighed material inside. The buffer spring 17 is used to block the mutual influence between the two groups of vibration motors.
